Domain Restrictions for Inverse Functions
When finding inverse functions, domain restrictions may be necessary to ensure the inverse is a function. For functions involving even roots, only the principal (positive) square root is used: where . Key formulas include expressions such as y = \sqrt{x}. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 5: Rational Exponents and Radical Functions.
